I have an NSR F1, which has the King 21 long can motor (21.4k /350gr). It wasn't as fast as the NSR anglewinders, which use the same motor and I was fooling around trying figure out why. I also wanted to try the NSR Shark EVO 28 (28k/200gr). I have been trying to come up with a good gear configuration for both motors and I'm not having any luck. The NSR anglewinders using the same King 21 motor use a 13t pinion and 31t gear (2.4 ratio). The inline gearing used in the F1 is 10/27 (2.7 ratio). I don't know why they would do that, especially since the F1 has a smaller diameter tire than the anglewinders. NSR sidewinders that use the Shark 25 (25k/ 180gr) use 11t/32t gearing (2.9 ratio). I reasoned with a 28k motor I could use a 3.0 ratio, given more rpm and torque.
The problem I am having is finding the right pinion and crown combination for F1 that gives me a 2.4 ratio with the Evo King or a 3.0 ratio with the Shark 28.. The ones I have on hand that fit each other, for either motor, don't yield great performance. The other possibility is I have no idea what I'm doing and have come to all the wrong conclusions about the gear ratios.
